WEATHER-STRIPPING.

SPECIFICATION forming part of Letters Patent No. 445,544, dated February3, 1891.

Application filed January 27, 1890. Serial No. 338,320, (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. Cosrnn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new'and useful Improvementsin W eatl1er-Stripping,ofwhich the following is a specification, reference'be ing had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My invention relates to improvements in weather-stripping of the classwherein a flexible element, as of rubber or the like, is employed forclosing interstices around windows, doors, &c.

The objects of my improvements are to provide a flexible weather-stripadapted for use with the conjoined employment of a rigid securing-stripor element, and which will at once embrace durability, eifectiveness,simplicity, and economy in its employment and construction, the sameconsisting in the matters hereinafter set forth, and pointed out in theappended claims.

In the accompanying, drawings, Figure 1 is a detail, mainly intransverse section, illustrating the manner of employing my improvedweather-strip between the meetingd'ails c f of the upper and lower sashEF, respectively, of the window. Fig. 2 is a broken detail in elevationof my improved weather-stripping. Fig. 3 is a transverse section of thesame. Fig. l is a detail in transverse section of the flexible strip.

Referring by letter to the said several views, the flexible stripconsists of a main or interstice-closing portion A, and a web B. Thisweb B may be formed integral with or suitably to said main portion A,and has at its free end a heel b, the purpose of which will behereinafter explained.

D designates astrip made of metalor other suitable rigid material, whichis bent or othwise suitably shaped to embrace said Web B,

and is supervened intermediate the web B, and the head of the nail orother device which secures the strip in position, and said web is fixedwithin said embracingstrip by means of a filament h. The heel l) of the.web is secured within said embracing-strip inside of the location of thefilament therein and thereby prevents the 'withdrawal of the Web fromits connection with said embracing-stri p. The most desirable materialemployed in making the said strip is rubber, the same being as pure asthe varying conditions of atmosphere, temperature, &c., to which it isexposed will warrant with a view to durability. The main portion A ispreferably of hollow cylindrical form,for reasons both of economy in theemployment of the material and the greater degree of flexibility whichconformation insures in' contradistinction to a solid construction.

Having now described my invention, what I believe to be new, and desireto secure by Letters Patent, is

1. As an improved article of manufacture, the herein-describedweather-stripping, consisting of a flexible strip having an enlargedmain or interstice-closing portion, a web extending therefrom, andhaving a heel at its free end, a rigid strip embracing said web, andmeans located between said heel and the main portion of the flexiblestrip for securing said web and embracing-strip together.

2. As an improved article of manufacture, the herein-describedweather-stripping, consisting of a flexible strip having an enlargedmain or intersticeclosing portion, as A, a web as B, extending therefromand havinga heel, as b, at its free end, a metallic strip, as D, bent toinclose said web, and a filament, as b, for securing said web andmetallic strip together.
